Using Source Mode
Providing Loop Power
The calibrator provides loop power at 28V or 24V dc. The 28V setting provides enough current for two or three
When loop power is enabled, the mA (middle column) jacks are dedicated to sourcing and measuring the current loop. This means that the SOURCE mA, measure RTD, and measure and source Ω functions are not available (see Table 8, later in this manual.)
Connect the calibrator in series with the instrument current loop as Figure 16 shows. Proceed as follows to source loop power:
1. Press sfor smode.
2.Note that following Loop Power, Disabled is highlighted. Press e.
3.Use the uor darrow keys to select Enabled 24V or Enabled 28V.
4.Press e.
5.Press the Done softkey.
